Unprocessable Entity – The ‘consumerName’ field is missing

I understand you want to offer the ‘Direct Debit’ (incasso) payment method on your form? In the Pronamic Pay payment feed settings of the Gravity Forms, you need to assign text fields to the ‘Account Holder Name’ and ‘Account IBAN’ fields on the tab ‘Fields’.

Please note that if you want to offer one-off payments with SEPA Direct Debit, this needs to be enabled for your account by Mollie.

You can add a Payment Methods field (from the ‘Payment Fields’ group) to your Gravity Forms form, in which you can select from which payment methods a customer can choose.

Can you elaborate a bit on what you’re trying to accomplish exactly? It’s not clear to me. Are you trying to offer SEPA Direct Debit or to hide this method on the form?

SEPA Direct Debit is usually used for the recurring payments, for which the first payment has been completed with iDEAL, Bancontact or SOFORT. However, it is possible to let Pronamic Pay create a “mandate” at Mollie — required for SEPA Direct Debit — for a first payment through SEPA Direct Debit by setting the “Account Holder Name” and “Account IBAN” fields, but it is more prone to user input errors compared to using a first payment through iDEAL/Bancontact/SOFORT. In test mode, Mollie will not automatically update a SEPA Direct Debit payment to the ‘completed ‘Paid’ status. Instead, you need to manually update the payment status and then request the the payment status within WordPress again. To update the payment status at Mollie, you can use the URL listed at WordPress admin → Pay → Payments → [ Choose payment ] → Meta box ‘Mollie’ → Click tr_XXXXXX link → Change Payment State.
